Update IAP plugin 1.19 problem: no known instance method for selector 'introductoryPrice'

Hello,

I have a problem after update the IAP plugin to 1.19. To do it I removed the previous version before the update and after this I clicked import on the services window. The Xcode used on Unity cloud build is 9.0. Unity version used 2018.1.0f2

The error on UCB is this:
/BUILD_PATH/GameName.ios-ci-master/temp.XXXXXX20180523-3651-160uhpz/Libraries/Plugins/UnityPurchasing/iOS/UnityPurchasing.m:577:85: no known instance method for selector 'introductoryPrice'

There are more errors like this but for 'numberOfPeriods', 'subscriptionPeriod' and 'numberOfUnits'

I have seen this code was added on UnityPurchasing.m after the update, it seems the problem because all the errors lines are here, but I don't know how to solve it


Can someone help me with this please?

Thanks!!!

 

@jesusrl Does this occur in your local build? What version of Unity are you using? Is this error during the IAP import/upgrade?

 

We are also experiencing this on Unity 2017.3.1p1.
Unity IAP was imported with no obvious issues and we didn't have a previous version of the Unity IAP asset installed (as this was the first time we had attempted to use it).
No errors reported on Windows, but something seems to be amiss when building on iOS, because we are getting very similar errors in UnityPurchasing.m

 

To be clear, the error occurs when you are building the project locally in XCode?

 

Yes that's right. No issue on my local machine running Windows, but same code fails to build on XCode.
All we have done up to that point was download and import the asset.

From what @jesusrl said, it seems the previous version of the asset was working fine for him on XCode, but we are coming to this new and don't have experience of 1.18

 

I just tested the sample project with Unity 2018.1.0f1, IAP 1.19 and XCode 9.3 without issue. Can you try building the sample project available here? https://forum.unity.com/threads/sample-iap-project.529555/

 

Jesusrl is my colleague .

We are having this problem in UCB and Unity 2018.1.0f2. Havent tried local build with 1.19. 1.18 worked fine.
UCB job is setup to use Xcode 9.0.

 

Same thing is happening for us: Unity 2017.3.0f3

 

Same thing is happening for us: Unity 2017.4.1f1

i see this msg in console:

Using configuration builder objects
UnityEngine.SetupCoroutine:InvokeMoveNext(IEnumerator, IntPtr)

I downloaded 1.17 version from here:

https://forum.unity.com/threads/unity-iap-versions-1-16-and-1-17-available-for-download.527432/

and it's work fine.

 

Same issue only for ios. Windows and Android build ok.
Unity Version: Unity 2017.3.0f3
IAP version: 1.19.0
Building with Unity Cloud build


/BUILD_PATH/PRODUCTPATH/temp.XXXXXX20180528-5805-tfev50/Libraries/Plugins/UnityPurchasing/iOS/UnityPurchasing.m:577:85: no known instance method for selector 'introductoryPrice'
Same for: numberOfPeriods, subscriptionPeriod, numberOfUnits

 

We've updated everything, deleted the project, uninstalled/reinstalled the unity package, reconnected to unity dashboard and updated all xcode and OSes etc. Same thing's happening

 

Unity 2017.3.1f1 , just upgraded to IAP 1.19. and I am receiving the very same error. Only when I build in xcode; when run from unity on desktop, everything is fine. I happened with IAP upgrade; previous version worked well.

 

@Kaven01 What version of XCode are you using? I tested with 9.3 without issue.

 

I suspect it's only older XCode versions, that have the errors. I couldnt reproduce when I built locally on my machine where I have Xcode 9.3 installed. It turns out our build server is on XCode 9.1 and it was that machine which was reporting the errors for us.

So it will be interesting if anyone can reproduce on XCode 9.3, or whether this definitely fixes it. We are in process of updating our build server to test...

 

OK I think I know what has happened and why so many people are having this issue: It is indeed the updating to Xcode 9.3 ( 9.4 ) that solves the issue but if you see my message above I said that I updated them all. Now the problem was the new xcode was not appearing under updates on our macs. One has to search for xcode and press the "grey" install button.

 

Downgraded to 1.16 using Xcode 9 on 10.12.6 and it worked.

Didn't want to upgrade my entire system just for the IAP asset.

 

You'll need that version of XCode to build for the latest iOS

 

How to solve this error?

 

Have you followed the suggestions in this thread? You may need to upgrade XCode. If you continue to have issues, please share what versions of Unity, IAP and XCode that you are using and steps to reproduce.

 

Thank you. XCode updation solved the issue.
